Food and Finance

I just read Michael Pollan’s book, In Defense of Food, and what struck me was the parallels between the evolution of food and the evolution of finance since the 1970s. This will only confirm my critics’ belief that I see the same thing everywhere, but bear with me for a minute.

Pollan’s account, grossly simplified, goes something like this. The dominant ideology of food in the United States is nutritionism: the idea that food should be thought of in terms of its component nutrients. Food science is devoted to identifying the nutrients in food that make us healthy or unhealthy, and encouraging us to consume more of the former and less of the latter. This is good for nutritional “science,” since you can write papers about omega-3 fatty acids, while it’s very hard to write papers about broccoli.

It’s especially good for the food industry, because nutritionism justifies even more intensive processing of food. Instead of making bread out of flour, yeast, water, and salt, Sara Lee makes “Soft & Smooth Whole Grain White Bread” out of “enriched bleached flour” (seven ingredients), water, “whole grains” (three ingredients), high fructose corn syrup, whey, wheat gluten, yeast, cellulose, honey, calcium sulfate, vegetable oil, salt, butter, dough conditioners (up to seven ingredients), guar gum, calcium propionate, distilled vinegar, yeast nutrients (three ingredients), corn starch, natural flavor [?], betacarotene, vitamin D3, soy lecithin, and soy flour (pp. 151-52). They add a modest amount of whole grains so they can call it “whole grain” bread, and then they add the sweeteners and the dough conditioners to make it taste more like Wonder Bread. Because processed foods sell at higher margins, we have an enormous food industry pushing highly processed food at us, very cheaply (because it’s mainly made out of highly-subsidized corn and soy), which despite its health claims (or perhaps because of them) is almost certainly bad for us, and bad for the environment as well. This has been abetted by the government, albeit perhaps reluctantly, which now allows labels like this on corn oil (pp. 155-56):

“Very limited and preliminary scientific evidence suggests that eating about one tablespoon (16 grams) of corn oil daily may reduce the risk of heart disease due to the unsaturated fat content in corn oil.”

With this fine print disclaimer:

“FDA concludes that there is little scientific evidence supporting this claim. To achieve this possible benefit, corn oil is to replace a similar amount of saturated fat and not increase the total number of calories you eat in a day.”

Unfortunately, nutritionism is pretty much bogus science. The major claim of nutritionism over the past thirty years–that fat is bad for you–turns out not to have any foundation at all.*

What does this all have to do with finance? Roughly speaking, read academic finance for nutritionism; the financial sector for the food industry; subprime loans, reverse convertibles, and CDOs for highly processed food claiming to improve your health but actually killing you; current disclosure laws for the FDA-approved health claims on corn oil; thirty-year fixed-rate mortgages and index funds for the neglected, unsubsidized, unadvertised fruits and vegetables in the produce section; the OCC and OTS for the FDA; and the long-term increase in obesity and diabetes for the long-term increase in household debt.

In both cases, you have an industry that earns profits by convincing people to do things that are not in their long-term interests; that, in the process, creates negative externalities for the rest of society; and that has cowed regulators into submission, if not outright cheerleading. In both cases, the industry defends itself from critics by saying that it is simply providing what customers want, and hence any new constraints (even, say, accurate organic labeling laws) constitute a paternalistic intrusion into people’s economic freedom. And in both cases, the industry claims that if it isn’t allowed to continue on its current course, the economy as a whole will suffer. (After all, our corn- and soy-based diet is what enables the industry to provide huge numbers of calories at low cost.)

One big difference is that when it comes to the food system, there is a fair amount you can do to protect yourself and your family from its unhealthy effects (if you have the money). With the financial system, it’s a bit harder.

* It’s a bit more complicated than that, so before you take this as advice, read Part I, Chapter 5.
